Aha! We’re finally getting insight into what prompted Solange to beat the brakes off Jay Z (while wife Beyonce stood by idly twiddling her thumbs) on an elevator back in May.

Dollar, dollar bills, yall.

At least that’s the story we’re getting from Queen Bey herself. Mrs. Carter vaguely references the now infamous fisticuffs between her husband and her kid sister on a newly-released remix of her single “Flawless” — which features femcee Nicki Minaj.

“We escalate, up in this bitch like elevators. Of course, sometimes shit goes down when it’s a billion dollars on an elevator,” Bey croons as the clank of a cash register chimes in the background.
